Product Description

Precision differential probes allow for safe, accurate measurements between two voltage points where neither point is referenced to ground and high accuracy is required.

Model CT3685 features a fixed 10x attenuation setting, 50 MHz bandwidth and ±700 V maximum differential.

Compatible with oscilloscopes from all major manufacturers, the probe is powered by a universal power adapter.

  • Up to ±700 V differential
  • 50 MHz bandwidth (-3 dB)
  • High accuracy ±1%
  • Safety certified
  • Small size
  • Good CMRR
  • Reference SI-51

Applications include:

  • Precise power semiconductor device measurements
  • Switching power supply design
  • Precise measurement of power converters
  • Precise measurement of motor drives

Kit comes in foam-lined case and contains:

  • Differential probe
  • (2) Hook probes, black & red
  • Power adapter, 9 V 500 mA, CT3723
  • User manual
